Willian expects John Terry's Chelsea career to come to an end this summer.
Terry, 35, made his debut for the Blues in 1998 and has racked up nearly 700 appearances during a trophy-laden time in west London.
This, though, looks set to be Terry's last campaign at Stamford Bridge, with the defender recently confirming he will leave at the end of the season.
Chelsea were quick to highlight that no decision had been taken on his future, but the defender says there have been no negotiations since his declaration.
Terry wants to extend his contract past the summer, but team-mate Willian feels the long-serving defender will soon be departing.
"I think he would like to stay longer with us, but unfortunately it seems he won't be able to remain as a Chelsea player," Willian told Squawka.
"The club won't probably extend his contract. I can just wish him the best of luck for the rest of his career."
The Brazil international added: "He is definitely one of the greatest or maybe the greatest player of Chelsea's history.
"He's won everything for this club. He is respected by all of us."
